摘　　要：在超级电容储能式无轨电车的充电控制系统中,外部的扰动会使得控制系统的输出控制性能降低,从而导致系统的噪声放大。为了增强控制系统的鲁棒性和自适应能力,基于跟踪微分器提出了一种新型的非线性控制方法,提高了超级电容储能式无轨电车的充电控制性能,优化了系统的输出电流电压的控制曲线。针对控制参数变化和调节的问题,加入Ziegler-Nichols的频域响应法(简称ZN法)来整定控制参数。通过仿真及试验分析,验证了所提控制算法的有效性,对于系统的输出控制性能有明显的提升,解决了系统快速性和超调之间的矛盾,从而实现了超级电容储能式无轨电车高效快速地充电。In charging control system of trolley bus, the output performance of the control system would be unstable caused by external turbulent, which results in the noise amplified. To enhance the robust and adaptive of control system, a new no-linear control method was proposed based on tracking differentiator to improve the charging control performance of ultra-capacitor trolley bus and optimize the curve of the output current and voltage of the system. Aiming at the problem of control parameter variety, a Ziegler-Nichols method was used to adjust the parameter. Simulation and test results completely proved that the proposed method was effective, which improved performance of the control system apparently, solved the contradiction between rapidity and overshoot, and realized quick and smooth charging for the super-capacitor energy storage trolley bus.
